It is located at the western foot of the peninsula. There is a 50 m passage at the entrance. After the passage there is a cylinderical cavern, this leads to the basement of the cave.
The stalactite and stalagmites inside the cave were formed over 15 thousand years. Besides its fascinating beauty the cave is famous for its atmosphere which is beneficial to asthmatics. Following the rumors that asthmatics benefited from breathing the air in the cave, scientists analyzed a sample of the air to verify the fact that the air was indeed beneficial to patients suffering from non-allergic asthma. They found that the air in the cave contains 10 to 12 times more carbon dioxide than normal air and has 95% humidity.
Temperature in the cave is a comfortable 22 degrees centigrade. Both the radioactivity and ionization in the cave may contribute to the benefits derived from breathing the air in the cave.
